-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello, I found, that FS doesn't maintain D-Channel's state correctly. I have a PRI with disabled layer 2 and 3 on TDM side. When FS starts up I get this on console: 2009-01-16 08:16:10 [DEBUG] ozmod_isdn.c:1441 zap_isdn_run() ISDN thread starting. 2009-01-16 08:16:10 [DEBUG] Span:0 Q.921() Starting trunk 0xae411008 (sapi: 0, tei: 0, mode: PTP TE) 2009-01-16 08:16:10 [DEBUG] Span:0 Q.921() Sending SABME 2009-01-16 08:16:10 [DEBUG] Span:0 Q.921() Sending frame - ----------------- Q.921 Packet [Outgoing] --------------- SAPI: 0, TEI: 0, C/R: Command (0) Type: U Frame (SABME) P/F: 1 Q.921 state: "TEI Assigned" (4) [flags: ----] - ---------------------------------------------- 2009-01-16 08:16:10 [CONSOLE] switch_loadable_module.c:857 switch_loadable_module_load_file() Successfully Loaded [mod_openzap] 2009-01-16 08:16:10 [NOTICE] switch_loadable_module.c:141 switch_loadable_module_process() Adding Endpoint 'openzap' 2009-01-16 08:16:10 [NOTICE] switch_loadable_module.c:239 switch_loadable_module_process() Adding Application 'disable_ec' 2009-01-16 08:16:10 [NOTICE] switch_loadable_module.c:259 switch_loadable_module_process() Adding API Function 'oz' 2009-01-16 08:16:10 [DEBUG] Span:0 Q.921() New packet received (3 bytes) - ----------------- Q.921 Packet [Incoming] --------------- SAPI: 0, TEI: 0, C/R: Response (0) Type: U Frame (DM (Disconnected Mode)) P/F: 1 Q.921 state: "TEI Assigned" (4) [flags: ----] - ---------------------------------------------- So TDM side tells FS that the link is down: but when I check d-channel's state FS tells me that it is UP: freeswitch@ippbx-prod-node0> oz dump 1 16 API CALL [oz(dump 1 16)] output: span_id: 1 chan_id: 16 physical_span_id: 1 physical_chan_id: 16 type: DQ921 state: UP last_state: DOWN cid_date: cid_name: cid_num: ani: aniII: dnis: rdnis: cause: NONE When I do an outbound call FS throws no error or warning that the link isn't up and gives the call a try. regards helmut -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (MingW32) iEYEARECAAYFAklwNnsACgkQ4tZeNddg3dzjKQCbBDU/SSOyKbD2JGcJFOJZDyBQ nI0An3CFp9HIuTB0cQWT0iJ1Rlx1+yGk =ycwj -----END PGP SIGNATURE-----
